My 20v is running really rich. When it is cold it runs fine, but as the car gets warm (to the first dash on the gauge) it develops a shudder and bogged down performance when accelerating. Exhaust smells of unburnt fuel.
I've got new plug wires on it along with a new coolant temperature sensor (recommended by a audi/vw guy) to no avail. The distributor rotor cap were replaced in '05...
The service engine soon light will come on when it idles for a while and hot but does not stay on. I am going to try to pull fault codes tomorrow but not sure it will pull anything if the light isnt on (thoughts?).
I was thinking O2 sensor but with no service engine light? I guess thats stupid, If the cars running poorly, its running poorly. If the light was so smart it would be lit up all the time. I dont need the light to tell me that.
Anyway, thanks in advance...
